Using silver 1.0mm thick brushed stainless steel craft box.
Wrinkle paint process cattle enclosures.
● metal knob cap, the cellular machine feet.
● the use of gold-plated RCA signal input lotus seat.
● Adopt with oxidation amber gold-plated output terminal.
● red cherry wood side of the decorative sheet, elegant and dignified.
● Blue LED power indicator.
● the performance of pre-thumb tube Description:
6N6T: high mutual conductance (S = 11mA / V), the amplification factor (u = 20), low internal resistance (Ri = 2KΩ) tube.
12AU7: well-known low transconductance, the high resistance of the communication measurement tube.
12AT7: the burning world "quite famous air excellent sense of wideband, low noise, u tube.
Product characteristics:
Power cattle output cattle imported audio-specific silicon silicon steel layer and section wound around technology. Cow power silicon steel: 114mm × stacked thick 60mm output
cattle silicon steel: 96mm × stack thickness 40mm. High-quality nylon frame, high-purity oxygen-free copper wire.
● Taiwan production W.L Wizard potentiometer volume control.
● input within the machine using Teflon silver plated shielded signal lines, strong anti-interference, transmission failure decreased.
● German WIMA red MKP polypropylene coupling.
● PCB model using sets of domestic production and some carbon film resistors; scaffolding welding models feature military Dahongpao metal film resistors, carbon film mix.
● high-voltage secondary rectifier, 5Z3P × 2 gall rectifier, four imported large pond and two inductor filter.
● reference to the improvement of the classic lines, famous 12AT7 x 2 voltage amplification, 12AU7 × 2 phase inversion, 6N6 × 2 cathode output driven, push-pull class AB
amplification. A wider frequency response, phase shift to smaller, higher fidelity.
● Transformer with epoxy potting, solid and reliable, high temperature, insulation, moisture, shock absorption and play a role, can greatly reduce the magnetic coupling through
the chassis to reduce resonance, and reduce noise.
